If Amazon Echo is a problem, why wouldn’t Microsoft Kinect also be? It is designed to detect all motion in the room, and take large pictures of everything and everyone, with audio.
I have one, but I refuse to plug it in, much less connect it or my XBox to the internet.
Anything connected is hackable, and if it is hackable, it probably has been hacked.
I use a paper planner for the same reason. It is not paranoia to question the wisdom of putting your every last idea in the public domain. Certainly, I put a LOT, but not all. Not even close.
